With luck, you have now done the easy part. The difficult part comes in
three months when the clocks go back. You will almost certainly have
some applications that run on wall clock time and don't tolerate
backward steps in time.

Incidentally, the reason that I ruled out Pakistan initially was that
the previous change was easily within living memory of anyone working in
IT, whereas the previous change in Morocco might be unknown to anyone
below their mid thirties. That conflicted with the statement that this
was the first ever use.

I think the earlier DST question was in relation to Morocco, as I seem
to remember a French connection. They will have the same consideration
when the clocks go back.

Thanks, anyone know howto do the DST things in Sun Solaris ? I am done
with BSD and Linux with tzdata + zic but duno how to do it on
Solaris.
I'll am very thankful to all those who replied to my thread and help
me to solve the DST issue.

The files live in /usr/share/lib/zoneinfo/src. Change the rules in the
asia file in that directory. You can then use the zic command to
create a replacement for the /usr/share/lib/zoneinfo/Asia/Karachi file.
